Based on the one or more user inputs and a determination that the device is connected to the network of the first type, the device sends the first file, but not the second file, to the server over the network of the first network type. Upon detecting that the device is connected to a network of the second network type, the device sends the second file to the server over the network of the second network type. | 2014-07-17 |
20140198688 | Method and Apparatus for Reducing Self Interference - A method, apparatus, and computer program product are provided to reduce self-interference in a transceiver. In the context of a method, a self-interference channel estimate may be determined. A reconstructed interference may further be determined based at least in part on the self-interference channel estimate and a signal to be transmitted and the reconstructed self-interference is caused to be subtracted from a received signal. According to a further embodiment, detection of a desired signal may be disabled while this process is repeated until a residual self-interference is below a threshold, at which point detection of the desired signal may be enabled. | 2014-07-17 |
